Abstract

The paper presents experimental studies of dielectric properties of nanofluids based on ethylene glycol and SC-TiO2 nanoparticles with average size of 15-40 nm with various mass concentrations. The dielectric permittivity both real part and imaginary part as a function of temperature and frequency were measured. Also, dependence ac conductivity on frequency, temperature, and mass concentration were investigated. Based on the curves of ac conductivity, dc conductivity was calculated, and 400 % enhancement in dc conductivity was exposed.

摘要

本文介绍了基于乙二醇和平均粒径为15 - 40 nm的SC-TiO₂纳米颗粒、具有不同质量浓度的纳米流体介电性能的实验研究。测量了介电常数的实部和虚部随温度和频率的变化。此外，还研究了交流电导率随频率、温度和质量浓度的依赖性。基于交流电导率曲线计算了直流电导率，发现直流电导率提高了400%。
